•» According to Zhang (2007) thermal expansion in the lower latitude is unlikely because of the reduced salt rejection and upper - ocean density and the enhanced thermohaline stratification tend to suppress convective overturning, leading to a decrease in the upward ocean heat transport and the ocean heat flux available to melt sea ice.

This allows the remaining heat to be transported down deeper into the ocean, causing an increase in ocean heat content over the long - term.

I agree that THC largely determines the amount of ocean heat transport to the North Atlantic, but this affects both sides of the Atlantic, not just Europe.

To some extent, this is again due to the factors mentioned above, but additionally, the models predict that the North Atlantic as a whole will not warm as fast as the rest of globe (due to both the deep mixed layers in this region which have a large thermal inertia and a mild slowdown in the ocean heat transports).

There is still debate over what kind of ocean circulation change causes the change in heat transport.

As the ocean circulation takes up the role of transporting heat poleward the atmospheric circulation spins down.

Suppose that there has been a multi-century increase in the poleward heat transport in the oceans due to internal variability, which warms the poles, reduces ice extent and albedos, and thereby warms the planet.

If tropical cyclone occurrence decreases, less of the heat is dissipated, and unless ocean circulation in some way compensates by transporting the additional thermal energy elsewhere (i.e. for example out of the «main development region» of the Atlantic) some day a storm will tap the enhanced energy source.
